ADJUSTABLE SHOE-HEEL.

To all whom it may concern:

Be it known that I, Sornao Qunvsno, a citizen of the Republic of Cuba, residlng at Habana, Island of Cuba, have invented av justable shoe heel, applicable to shoes or boots, and which may be held against movement when once adjusted. I

An object of the invention is to provide means for securing an adjustable cushion I heel on the heel of a shoe yieldably, in such wise that the cushion heel may be adjusted in different positions as Wanted or required, as it wears, so that the cushion heel may wear evenly.

A further object of the invention is to provide means to prevent the securing screw from pulling through the cushion or rubber heel, and after the heel has been once adjusted, to provide means to prevent the same from turning. 4

In practical fields the details of construction may necessitate alterations, falling within the scope of what'is claime I The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings Fi ure 1 is a view of a portion of a shoe,

showing the heel thereof in section, and the cushion heel applied thereto.

Fig. 2 is a bottom plan view.

Fig; 3 illustrates collective views of the several parts for securing the cushion or rubber heel to the heel of the shoe.

, Referring to the drawings, 1 designates a part of the heel portion of the shoe 2, whereas 3 denotes the adjustable cushion or rubber heel, which is circular or annular, as preferably shown. This c'ushion or rubber heel upon its under surface is provided with a depression {1. A plate 5, which is concavo convexo in crosssection, is provided. This plate'is yieldable and has a plurality of yieldable tongues 6, which engage corre- Specification of Letters Patent.

spondingly shaped recesses 7 of the depression, and when the plate is de )ressed upwardly, the tongues wedge or em ed into the end walls of the recesses 7, as shown at 8, thereby yieldably holding the cushion heel in place. The plate 5 has a-centraTaperture to receive the screw 9, which passes through the cushion or rubber heel as shown at 10, and is threaded into the heel 1. The screw also passes through the plate 11 which is arranged between the rubber or cushion heel and the heel 1. This plate 11 has upwardlyand downwardly struck up lugs or spurs 12 and 13 to embed into the heel 1' and the rubber or cushion heel 3, so as to prevent the rubber or cushion heel 3 from turning after having been once adjusted. The plate'5 constitutes means to prevent the head of the screw from pulling through the rubber or cushion heel 3, while the tongues 6 engaging th recesses 7 of the depression act to yieldably bear against the rubber heel, to more securely hold the same in place. The close-r the plate 5 is pressed to the rubber or cushion heel more secure the heel 3 is held in place. After the screw 9 has been unscrewed a cer-. tain distance, a suitable tool may engage the tongues of the plate 5, so that by turning the plate, the heel will rotate therewith, for adusting the same in different positions, so as to wear evenly. w The invention having been set forth, what is claimedoas new and useful is: 'In combination'with a shoe heel, a rubber cushion heel, the bottom face of the cushion heel having a depression extending upwardly substantially a half of the thickness of the-cushionheel, said depression being Patented Oct. 8, 1918. Application filed October 15, 1915. Serial No. 56,105.

plate being dished or bowed downwardly centrally and having the outer ends of said prongs V-shaped to engage the under cut end walls, and a screw passing centrally through said plate and threaded into the wmhien' and shoe heels, whereby upon 1 the serew against the action 0f the P1944333, the prongs will spread the ruhem on heel and cvercume the tendency rubber heel t0 contract 0r x'ecede from @123; of the shoe heel.

hesfibimany whereof I have signed my mamsse name to tins spemficanon 1n the presence oi ,twe subscm-blng Witnesses.
